SEPARABLE FASTENER.

Application filed March 8, 1921. Serial No. 450,737.

To all whom t may oon-cern.'

Be it known that l, FRED S. CARR, a citi- Zen of the United States, and a resident of Newton, in the county of Middlesex, Commonwealth of Massachusetts, have invented an Improvement in Separable Fasteners, of

which the following description, in connec-v tion with the accompanying drawings, isa specification, like characters on the draw ings representing like parts.

rlhis invention pertains to improvements in separable fasteners. It is among the objects of the invention to provide a superior separable fastener of simple and inexpensive construction.

In the drawings, which show a preferred embodiment of one form of my invention Figurel is a front elevation of two pieces of fabric carrying the stud and socket members, the latter being shown in dotted lines;

Fig. 2 is a section on the line 2-2 of Fig. 1, being partly in elevation;

Fig. 3 is a front elevation of the socket` vmember; and

Fig. A is a front elevation of the stud. Referring to the drawings and to the pre- Vferred form of my invention selected for illustrative purposes, I have shown a stud ofconventional form including a base 5, a head 6 and a neck 7. rlhe stud may besecured to its carrying fabric 8 in any suitable way, as by stitching 9.

The preferred form of socket member il-V lustrated does not include any casing, but is formed of a single piece of wire bent to provide the stud-receiving aperture 10 and to provide loop portions 11, lending resiliency to the socket and inculuding, adjacent the ends of the wire which forms the socket, adjacent eyes 12, 12 adapted to be sewn together when the socket isstitched to its carrying fabric 13 so that the resiliency of the socket will be rather evenly distributed around the same with no substantial tendency to increased spreading movement at that side of the socket where the ends of the wire are located. The loops 11 are preferably three in number, symmetrically disposed about the aperture, preferably about 90 apart as shown, and each is of a diameter approximating or even exceeding that of the aperture. The result is that the socket is quite resilient and spreads symmetrically when the stud is pressed into the aperture. This symmetrical spreading also reduces strain on the stitching e The socket illustrated 1s very thin, and is 'preferably substantially fiat.

While l have shown and described a preferred form of one embodiment of my invention, it will be understood that changes involving omission, substitution, alteration and reversal of parts, and even changes in the mode of operation, may be made without departing from the scope of my invention, which is best defined in the following claims.

1. A fastener socket formed of a single piece of wire providing al plurality of resilient loops arranged about a stud-receiving aperture, and'also having two stitch-receiving eyes, the two stitch-receiving eyes being adjacent each other and spaced from .the stud-receiving aperture by the end oortions of the wire, said end portions being of sufficient length so that the aperture may spread or expand substantially symmetricah ly when the stud is forced thereinto without putting an undue strain on the stitches which pass through said eyes and secure the socket to the carrying fabric.

2. A fastener socket formed of a single .piece of wire providing a plurality of resilient loops about a stud-receiving aperture and two stitch-receiving openings, one adjacent each end of the wire forming the socket, said stitch-receiving openings in adjacency to each other whereby a portion of the stitching securing said socket to its carrying fabric may hold in adjacency the terminal portions of the wire and tend to equalize the resiliency of the cooperating portions of said socket, said socket presenting two resilient wire portions between said stitch-receiving openings and Saidstud-re ceiving aperture.

3. A socket for separable fasteners formed of a single piece of wire and providing a stud-receiving aperture and a plurality of loops arranged about said aperture, said loops substantially closed to prevent entrance of the neck of the cooperating stud into said loops, and the end portions of said wire brought into adjacency and looped to provide stitch-receiving openings, said plurality of loops each approximating in diameter the diameter of said stud-receiving aperture.

fi. A separable fastener comprising, in

combination, a stud *having a head, a neck and enbaseY portion; a socket formed of a. single pica-of Wire and providing a vetudreceiving aperture7 the terminal portion-sofV the Wire-forming-said socket, being looped:- to provide adjacent stitch-receiving,-aperv ture, said Wire also providing loops about said stud-receiving` aperture, anchsaidgwirej:

l providing adjacent said loops and adjacent said terminal portione'langular fcorners-j wherein the neck of said studY may enter under lateral strain, the Wire formingithe socket being arched to Vopposedistortion thereofbeyond' its elasticlirnit Whensaid p stud and Socke-tare under lateralstrain,

5. A `fastener Socket formed of a Single piece of' W1re,*bentfto1ief1n a singlel plane and provided with three resilient substantially closed loops, the endelo'f said Wire extending outwardly from the .-studlreceiying aperturevr and terminating in stitch-receivingV ture spreads syn'nnetrically under pressure yfrom the Stud Without undue etrainonthe stitching which holds' the socketiniember to the Jfabric.
